ECU is under the bonnet at the front O/S by the jack under the black cover.

Thanks I'll take a look to see if it's been apart as its a 2000 and believe it needs to be split for chip change on that model

You are correct

dynachip already has them, he will do a straight swap/change if you find yours hasn't been done

Can they not be re-mapped without being re-chipped? If so how could you tell?

depends on what model/age you have, earlier ones have to have a chip soldered, later ones remapped, but what a difference when done!

It depends on which version of the engine ECU you've got. If the model number starts with MSB ******* then it's not 'flashable' so you need to change the chip within the ECU to a flashable one. Once this is done, the re-mapping can occur via the diagnostic socket.

If the ECU model no. starts with NNN then it already has a flashable chipset and can therefore be remapped immediately via the OBD diagnostic socket.
